Abstract: | The main objective of this paper is to find some concrete evidence of changing pattern of air temperature in Sri Lanka using secondary data available in different government and non-government organizations. The daily air temperature data (during the period 1961-2001) collected from the Meteorological Department and daily surface temperature data (during the period 1881-1981) collected from the NASA web site are the main data sources. 2 In addition to the GIS techniques such as surface interpolation, summarized by zones and geo-statistics, Regression and Time-series Analysis were used to achieve the set objectives. The study identified that the average temperature has increased in some areas such as Nuwara-Eliya, Anuradhapura, Colombo, Maha-Illuppallama, Hambanthota and Angunukolapalassa in Sri Lanka whilst some observatories depicted a declining trend of temperature and the area under high temperature is expanding. |
